NAME

       sane-dc25 - SANE backend for Kodak DC20/DC25 Digital Cameras

DESCRIPTION

       The  sane-dc25  library  implements a SANE (Scanner Access Now Easy) backend that provides
       access to Kodak DC20 and DC25 cameras.  At present, only the DC25  has  been  tested,  but
       since  the  code is based on a DC20 interface program, it is likely to work for that model
       also.

DEVICE NAMES

       The current version of the backend only allows one camera to  be  connected.   The  device
       name is always "0".

CONFIGURATION

       The contents of the dc25.conf specify the serial port and baud rate to use.  The baud rate
       specifies the maximum rate to use while  downloading  pictures.   (The  camera  is  always
       initialized  using  9600  baud, then switches to the higher rate).  On my 90MHz Pentium, I
       usually have no problems downloading  at  115200  baud  as  long  as  the  system  is  not
       excessively  busy  and  the "interrupt-unmask flag" is set in the IDE driver (hdparm -u1).
       Supported baud rates are: 9600, 19200, 38400, 57600, and 115200.

       The dumpinquiry line causes some information about the camera  to  be  printed  to  stderr
       during startup.  Note:  This is not compatible with saned, so make sure you don't have any
       dumpinquiry lines if you are using saned (i.e.  scanning  on  a  remote  machine  using  a
       network).

       Empty  lines  and lines starting with a hash mark (#) are ignored.  A sample configuration
       file is shown below:

              port=/dev/ttyS0
              # this is a comment
              baud=115200
              dumpinquiry

FILES

       /etc/sane.d/dc25.conf
              The backend configuration file (see also description of SANE_CONFIG_DIR below).

       /usr/lib/x86_64-linux-gnu/sane/libsane-dc25.a
              The static library implementing this backend.

       /usr/lib/x86_64-linux-gnu/sane/libsane-dc25.so
              The shared library implementing this  backend  (present  on  systems  that  support
              dynamic loading).

ENVIRONMENT

       SANE_CONFIG_DIR
              This  environment  variable  specifies the list of directories that may contain the
              configuration file.  On *NIX systems, the directories  are  separated  by  a  colon
              (`:'),  under  OS/2, they are separated by a semi-colon (`;').  If this variable is
              not set, the configuration file is searched in two default directories: first,  the
              current  working  directory  (".")  and  then  in /etc/sane.d.  If the value of the
              environment variable ends with the directory separator character, then the  default
              directories  are searched after the explicitly specified directories.  For example,
              setting SANE_CONFIG_DIR to "/tmp/config:" would result in  directories  tmp/config,
              ., and /etc/sane.d being searched (in this order).

       SANE_DEBUG_DC25
              If  the  library  was  compiled  with  debugging  support enabled, this environment
              variable controls the debug level for  this  backend.   A  value  of  128  requests
              maximally copious debug output; smaller levels reduce verbosity.

BUGS

       Known bugs/limitations are:

       I  haven't  figured  out  how to trigger an option reload following a "scan."  This causes
       problems when a new picture is snapped for example, the slider that is used to select  the
       picture from the camera may not be updated immediately.

       More general comments, suggestions, and inquiries about frontends or SANE should go to the
       SANE  Developers  mailing  list  (see  http://www.sane-project.org/mailing-lists.html  for
       details).   You  must  be subscribed to the list, otherwise your mail won't be sent to the
